' sHooK-Asonniiai -Be it known that I, V'ILLIAM N. BORDER, 4a

-citizen of the United States, yresiding at lit Dunlap, i thec'ounty ofGrundyand State of Missouri', have invented a new and usefulShock-Absorber; `and I do hereby declare the following to be a'full-,clean and exact "description of the invention, such as willenable othersskilled in the artto which it appertains to inake and usethe same.

This' invention relates to a newand useful shock absorber. l Y l As oneof the objectsof vthe invention, it is the aim, to provide a. simple,eicient and practical device of this nature, which will absorb thevibrations and strains of the body.

of a vehicle, in order to 'permit' the occupants thereof to ride with.ease and comfort;- A further object of the invention is to' provideacompound (ir/double spring' arrangement, so arranged as to insure.the'ab sorption otallf the vibrations, shocks and-- strains othebodyofthe vehile.` f

A further objectofthe inventionis the. `inclusion of means incombinationv Vwith the compound or double spring arrangement,

whereby the tension of the springs maybe regulated, for-doubly insuring.the absorb- Vingoftheshocks land vibrations of lthevehiclebo'dy,'particularly in case ofextra weightthe'reon- The inventioncomprises urtherfeatures and combination of parts, as hereinafter set`or th,slriown in the drawings and claimed.
